The entire low-carbohydrate versus low-fat diet argument is so prevalent that one would think that these are the only two options available for losing weight and staying healthy. Some experts even feel that the low-carb/low-fat debate distracts us from an even more important issue—our culture’s reliance on processed and manufactured foods.

The paragraph best supports the statement that

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. experts state that not all fats are equal, so we need not reduce our intake of all fats; just those that contain partially hydrogenated oils.
  2. important health concerns get overlooked when we focus exclusively on the low-fat versus low-carb question.
  3. low-carbohydrate diets lead to significant and sustained weight loss.
  4. processed foods can lead to many adverse health problems including heart disease, cancer, diabetes, and obesity.
